The teeth are bent in the direction of carding in any desired manner as described above to form thin cusps. will be accomplished. Other bending methods can be used to shape the teeth of the carding element into flat or curved surfaces. You can also bend the tip using any other bending device to create a cusp. It can also be formed.

The teeth are bent by approximately 0.003>n (approximately 0.08m5+), 0.005! (approx. It is preferable not to bend it by more than 0.13 mm). The teeth shown in Figures 16 to 18 are Hardened, but not exceeding approximately 57-58 on the Rockwell C scale hardness is preferred. This hardness is lower than the hardness normally imparted to metal wire clothing; It is not so large that the tooth breaks excessively due to brittleness during bending of the tooth tip. hardness range The range varies and is difficult to measure. The hardness is greatest at the tip of the tooth, and the hardness is greatest at the tip of the tooth. changes to become smaller towards the depth of the segment (where the tooth joins its base) ing. It is preferable that the bending point is about 0.03 an (about 0.08 an). Newly, the tips of the teeth are bent to form a cusp, which is different from grinding. The present invention Preferably done without grinding or other methods that would remove metal from the teeth. Yes.

If you use a profile wire with a carbon content lower than the normal carbon content, It has been found that the formation of acupoints or thin cusps is facilitated. car obtained The improved dinging action also justifies the short useful life of the clothing. bread Grinding or rolling the sides of the profile wire to form a thin edge before cutting 73! Punching work, hardening work, or resolting work! go through the hassle It has been found that it is possible to manufacture teeth on a normal base without having to apply any degree.

The method of grinding metal cloth is to grind the metal at the tip of the tooth by grinding a small whisker on the leading edge of the point. Causes burrs. This stream also provides other improvements in carding performance. By lowering the nep count between points, the carding properties of metal clothing can be improved. Improved. Whiskers or streamers are very fragile and weak and therefore break down within a relatively short period of time. effectiveness under high speed carding conditions is compromised.

On the other hand, the present invention has been developed by bending the tips of the teeth with little or no grinding. , a curved point consisting of a significant amount of metal oriented generally in the direction of carding It forms the These cusps are suitable for grinding even under high speed carding conditions. It has a longer lifespan than the whiskers, streamers, etc. that occur.

By rolling the cusp with little or no grinding of the tooth tip. , the shape and extent of the anterior protrusion of the cusp can be more easily controlled, and thus the maximum amount of The metal forms a sharp point, thus providing the best performance characteristics and longest life.

Clothing manufactured in accordance with the invention shall be ground if its use requires grinding. It can also be ground.

The conventional technology, except for grinding, usually involves hitting the tips of the teeth of the metal clothing with something. However, the present invention is not related to such teachings of the prior art. It is.

Although the preferred embodiments of the present invention have been described above using special terms, The details are for illustrative purposes only and do not depart from the spirit and scope of the invention. It should be understood that various modifications are possible without the above.
